In the drawings:

Fig. l shows, in side elevation, a device constructed in accordance with the invention, the body being lowered;

Fig. 2 is a top plan, on the line 2-2 of Fig. l;

Fig. 3 is a side elevation, showing the body raised at both the forward and rear ends;

Fig. 4 is a perspective showing a portion of the lifting mechanism.

In the drawings there is shown a wheelmounted frame lil, on which the dumping body i l is adapted to be carried, as shown in Fig. l. A supporting member 3l for the front of the dirmping body li is provided. Brackets 35 are secured to the rear end of the supporting member 3l, and are pivoted at 33 to the rear end of the frame lil, the construction being such that the` supporting member 3l can swing vertically. At its forward end, the supporting member 3l is supplied with pins 38 or the like, received slidably in guides 3% secured to the forward end of the body il. The body il, therefore, has a vern tical swinging movement with respect to the supporting member Si and a limited front and back movement with respect to the supporting member, as well.

A transverse brace i8 forms part of the frame l0, and slightly in front of the brace I8 there is a winch shaft l, which is journaled in the frame. A gear wheel 2i) is secured to one end of the winch shaft i9, the gear wheel meshing with a pinion 2l secured to an operating shaft 22 journaled in the frame EE) and in a supporting bracket Illa, secured to one side of the frame.

Lifting arms 2 are provided. At their forward ends, the lifting arms are pivot-ally mounted on the countershaft It, as shown in Fig. 4. The rear ends of the lifting arms 2l are connected by pivot elements 29 with the intermediate portion of the supporting member 3i. The forward ends of links 3@ are mounted on the pivot elements 29, and the rear ends of the links 30 are pivotally connected at B with the rear portion of the body I i.

Lifting members 2B are supplied, and the rear ends of the lifting members 28 `are pivotally connected at 32 to the intermediate portions of the links 30. As shown in 3, the forward or lower ends of the lifting members 28 have forks 33, adapted to receive the end portions of the countershaft M. The upper fingers 34 of the forks 33 are longer than the lower fingers of the forks and are adapted to rest on the countershaft i4.

The device is capable of two operations, one of which comprises elevating the body l I at both the front and rear ends, the other of said operations comprising raising the front end of the body only. Up to this point enough structure has been described to enable the reader to understand the first-specified operation, that is, raising the body at both ends, as in Fig. 3. That ope-ration will now be set forth, and the structure which brings about a raising of the front end only of the body Il will then be explained.

Suppose that the lifting members 28 are fulcrumed on the ends of the countershaft i4, in that the ends of the countershaft are received in the forks. When the operating shaft 25 is rotated, rotation is imparted to the winch shaft I9 through the gear train 24-23--2I--20- The flexible elements I 6 are wound on the winch shaft I9, the counter shaft i4 is carried backwardly on the tracks I2, the lifting arms 21 tilt the supporting member 3l, on its pivotal mounting 36, to the position of Fig. 3, and the lifting members 28, acting through the links 30, raise the body Ii with respect to the supporting member 3|, the body moving on the pivotal connection 38-39 which unites it with the supporting member 3 I. The body I I may be held in the position specified, by operating the brake 26.

It is clear that if the forked ends 33 of the lifting members 28 were kept clear of the countershaft I4, the lifting members would not fulcrum on the countershaft, the links 30 would not be operated, and the rear end of the body II would not be raised to the position shown in Fig. 3, when the supporting member 3l is raised to the position of that figure. The means for accomplishing the result last-mentioned will now be described.

The lifting members 28 are connected by a transverse bridge 3l.. A latch 40 is pivoted at 40' to the forward end of the supporting member 3|. The latch Ml is pivoted to an operating member 4 I, slidable in a guide la on the supporting member 3l. A pin i2 may be used to connect the operating member I to the supporting member 3|.

When the parts are in the lowered position of Fig. l, the forks 33 of the lifting members 2B are behind and clear of the countershaft I4. By means of the operating member 4I, the person in charge swings the latch 4B until its rear end is under the bridge 3l on the lifting members 28. Thus, the lifting members 28 are connected to the forward portion of the supporting member 3I, as shown in dotted line in Fig. 3, the lifting inembers 28 are carried upwardly along with the supporting member 3I, the lifting members do not fulcrum on the countershaft Ill, the links 3i] are not operated, and the rear end of the body II does not rise to the position of Fig. 3, when the front end of the body is raised to the position of said figure.

What is claimed is:

In a wagon dumping mechanism, a frame, a rearwardly and upwardly inclined track on the frame, a body carried by the frame, a body-supporting structure pivotally connected to said body at the front of the body and pivotally connected to` said frame at the rear thereof, a link pivotally connected at one end tosaid supporting ystructure intermediate the ends thereof and at the opposite end to the rear of said body, a transversely extending shaft carried by said track, means for moving said shaft longitudinally of said track, a lifting arm pivotally connected to said shaft at one end and pivotally connected to said supporting structure at the opposite end, whereby when said shaft is moved rearwardy and upwardly along the track said supporting structure will swing said body at the front upwardly, and a straight lifting member pivoted at one end to said link intermediate the ends of theV link, the end of said lifting member opposite its connection with said link being forked and normally positioned to` be engaged by said shaft and moved rearwardly and upwardly thereby, whereby said link and the rear of said body will be lifted. and the load will be transmited directly through the forked link from the body to the sha ft and track.
